Marvell introduced a new 60 Gbps Ethernet Switching chipset aimed at a new generation of Ethernet switches featuring 10 GbE uplinks, dedicated ports running at 12 Gbps for stacking, and advanced QOS using policy control, all at full wire speed. New features available in the Prestera-DX250/260/270 packet processors include:
- Policy Control List (PCL) — Wire speed policy control guaranteeing IPv4/v6 Security, VLAN, and QoS ACL rules.
- SecureControl — A new approach to CPU traffic management functionality that enhances security by preventing problems, such as “Denial of Service” attacks.
- Distributed Switching Architecture (DSA) — an integrated approach enabling fabric-less stacking.
- HyperG. Stack (HGS) — Standard XAUI interface, which can be configured as 10 GbE or tuned to 12 Gbps enabling full wire rate back-to-back and stackable topologies.
- The Prestera-DX250 offers 24GbE ports, while the DX260 offers 24GbE- plus two 10GbE-ports and the DX270 offers 24GbE- plus three 10GbE-ports.
Sampling is underway to key OEM customers. http://www.marvell.com
